Super tweeter

Abstract

A super tweeter includes a magnetic base, a voice coil, a frame annularly mounted to the magnetic base, a central supporting member mounted on a central portion of the magnetic base, a diaphragm, an annular inner supporting member, and an annular outer supporting member. The diaphragm is connected between an annular outer side of the annular inner supporting member and an annular inner side of the annular outer supporting member. An annular inner side of the annular inner supporting member is engaged with the central supporting member. An annular outer side of the annular outer supporting member is engaged with the frame. The annular inner supporting member and the annular outer supporting member cause the diaphragm to vibrate in a balanced manner, generating super high frequency range of sound waves.

1. A super tweeter comprising:
 a magnetic base; 
 a single voice coil; 
 a frame annularly mounted to the magnetic base; 
 a central supporting member mounted on a central portion of the magnetic base; 
 a diaphragm including an annular inner side and an annular outer side, the diaphragm made of a light and rigid material; 
 an annular inner supporting member including an annular inner side and an annular outer side, the annular inner supporting member made of a resilient and soft material different from that of the diaphragm; and 
 an annular outer supporting member including an annular inner side and an annular outer side, the annular outer supporting member made of a resilient and soft material different from that of the diaphragm; 
 wherein the diaphragm is attached to the annular outer side of the annular inner supporting member and the annular inner side of the annular outer supporting member such that the combination of the single voice coil with the diaphragm is located between the annular inner supporting member and the annular outer supporting member, the annular inner side of the annular inner supporting member is engaged with the central supporting member, the annular outer side of the annular outer supporting member is engaged with the frame so that the single voice coil is spaced apart from the annular inner supporting member and the annular outer supporting member, the annular inner supporting member and the annular outer supporting member causing the diaphragm to vibrate in a balanced manner, generating super high frequency range of sound waves. 
 
   
   
     2. The super tweeter as claimed in  claim 1 , wherein the voice coil is glued at a position below the diaphragm. 
   
   
     3. The super tweeter as claimed in  claim 1 , wherein the magnetic base includes a T-iron, a magnet, and a pole plate, and wherein the voice coil is positioned in a gap between the T-iron and the pole plate. 
   
   
     4. The super tweeter as claimed in  claim 3 , wherein the central supporting member is mounted on a central portion of the T-iron of the magnetic base, a central dome being mounted on top of the central supporting member, the annular inner supporting member being engaged between the central supporting member and the central dome. 
   
   
     5. The super tweeter as claimed in  claim 1 , wherein the magnetic base includes a U-iron, a magnet, and a pole plate, and wherein the voice coil is positioned between a gap between the U-iron and the pole plate.
